BACKGROUND This paper investigates patients' satisfaction with various aspects of fertility care and seeks to determine to what extent fertility specialists are able to assess patient satisfaction. Patients' experiences with in-vitro fertilization (IVF) services and facilities have been compiled and examined in order to discover whether patients' satisfaction is correlated to psychological fact...

Female fertility declines dramatically with age, and childbearing at older maternal ages has significant medical consequences for mother and infant that are well-known to health professionals. Despite this, the average maternal age in the United States continues to rise. Many factors likely contribute to this secular trend; to date, no research has examined whether American women are aware of t...

The fertility or sterility of a male depends on several factors, among which are the chemical constituents of the semen, the number, morphological integrity, motility, metabolism and viability of the spermatozoa. These factors, of course, are interrelated in effecting fertility or probability of fertilization. Although in normal matings the number of spermatozoa in the ejaculate is much greater...

Heritable changes of phenotype arising in plant ontogenesis by the influence of environmental factors belong to the most intriguing genetic phenomena. An unusual inheritance pattern was detected during examination of male fertility restoration in the CMS-inducing "9E" type cytoplasm of sorghum: Rf-genes were functional in self-pollinated progeny of F(1) hybrids yet were either not expressed or ...

This paper examines potential relations between factors related to fertility and the access to and use of natural resources in Petén, Guatemala. The Petén forms the heart of the Selva Maya, the largest lowland humid forest in Mesoamerica. The rapid in-migration of subsistence maize farmers has converted much of the Petén’s forests to agricultural fields. Population dynamics have been transforme...

The male uro-genital tract is susceptible to gram-negative bacterial infections that produce a state of inflammation, particularly in the testis and epididymis. Development of germline stem cells into motile spermatozoa takes place in these organs and thus any impairment therein has a direct effect on male fertility. A number of factors are known to impair male fertility including environmental...

Fertility is being determined by the actual bearing of children and or the demand for children. It is a measure of rate at which population increases to itself by relating number of births to size of some selection of population such as number of married couples or number of women of child bearing age [1-3]. Fertility is high in Bangladesh even by the principles of developing countries. The red...

osting by E Abstract The management approach to patients with pelvic endometriosis is multidimensional. One must consider several factors such as patient’s age, parity, extent of the disease, and menopausal status when planning treatment strategies. The main goals of therapy are targeted at symptom control and achieving fertility in women who so desire. Medical and/or surgical therapies can be ...

To guide soil fertility investment programmes in sub-Saharan Africa, better understanding is needed of the relative importance of soil and crop management factors in determining smallholder crop yields and yield variability. Spatial variability in crop yields within farms is strongly influenced by variation in both current crop management (e.g. planting dates, fertilizer rates) and soil fertili...

In settings of high fertility and high HIV prevalence, individuals are making fertility decisions while simultaneously trying to avoid or manage HIV. We sought to increase our understanding of how individuals dually manage HIV risk while attempting to achieve their fertility goals as part of the project entitled HIV Status and Achieving Fertility Desires conducted in Zambia in 2011. Using multi...
